HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 746,132, dated December 8, 1903. Application filed July 20,1933. Serial No. 166,330. (No model.)

To all whom it may concern: 7

Be it known that I, 'WILEY F. NANNEY, a citizen of the United States, residing at Ben Franklin, in the county of Delta and State of Texas, have invented anew and useful Hay- Press, of which the following is a specification.

This invention relates to baling-presses, and more especially to that type of balingpresses in which the plunger is actuated by a pair of toggle-links and is retracted by a spring after the completion of each stroke.

The object of therinvention is to provide an improved press of the type specified in which the stroke of the plunger may be readily adjusted to suit the compressibility of the material acted upon and the degree of compression required therefor. I v

A further object of the invention is to improve the operating mechanismin a press 'of the type described so as tofacilitate the operation by making the movements of the plunger smooth and regular and by providing for a considerable dwell after each stroke of the plunger to permit the insertion into the press of fresh material for compression. With the objects above stated and others in view, which will appear as the invention is more fully disclosed,'the same'consists in the construction and combination of parts of a baling-press hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which there is exhibited a preferred form of embodiment of the invention, it being understood,'however, that various changes in the form, proportions, and exact mode of assemblage of the elements may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

In the drawings, Figure 1 is a plan view'of Referring to the drawings in detail, B designates the base, comprising a longitudinal,

portion 1 and a transverse portion 2, rigidly connected therewith and arranged at right angles to the longitudinal portion. Thebase will be constructed of any suitable material,

bolted or otherwise fastened together to give by means of a collar .4, within which the shaft is rotatable, which issupported at the upper ends of three inclined braces 5, 6, and 7, arising from the base, as shown. At the upper end of the vertical shaft 3 is provided a sweep 8, which extends outward therefrom and has attached at the free end thereof a' whiffletree' 9 or other suitable draft appliance for the attachment of an animal to furnish power for operating the press. Near the lower end of the shaft there is rigidly connected therewith in a horizontal position the cross-bar 10, which forms a rotatory cross-' head, as will hereinafter be explained. The cross-bar 10 is provided at either'end with an upright pin 11, and the cross-bar is so attached to the shaft 1 that'the pins 11 are equidistant from the axis of the shaft. of the pins 11 is provided with a trip-lug 12,

having a cam-face and being adj ustably secured in position by'means of a set-screw.

At the end'of the longitudinal portionl of the base which'is most remote from the shaft 3 isprovide'd a press-box 13, in which reciprocates the plunger 14, provided'with' a head 15. The plunger is mounted for reciprocation on the base in any suitable manner, being preferably provided with ball-bearings to diminish the friction of operation thereof. Pivotally attached'to the rear end 'of'the plunger is a toggle-link 16, which is pivotally connected at its other end with a similar link 17, which is mounted for oscillatory movement upon the end of the longitudinal portion 1 of the base opposite the press-box. The links 16 and 17 are normally held in the position indicated in Fig. 1 by means of a spring 18, attached at one end to the link 17 and at the other end to a projecting arm 19,

which extends obliquely from the longitudinal portion 1 of the base to a suitable distance beyond the side over which the togglelinks work.

Mounted on the pivot-pin which connects the toggle-links l6 and 17 is an arm 20, which is adapted to swing freely on said pivot and is provided at its free end with a hook 21, as shown. The arm 20 is held normally in the position indicated in Fig. 1 by means of a spiral spring 22, attached at one end to one of the toggle-links and at the other end to the arm 20.

The operation of the press is as follows: Motion being imparted to the rotary vertical shaft 3 by a draft-animal attached to the whiffletree 9, the transverse bar 10 will be caused to rotate about the axis of the shaft 3 and the pin on one end of said bar will engage with the head 21 on the arm 20 and will draw the hook and arm inward toward the median line of the machine, as indicated in dotted lines in Fig. 1. This inward movement of the arm 20 and the hook 21 on the end thereof carries with it, of course, the pair of toggle-links 16 and 17 and brings them more nearly into alinement with the longitudinal portion of the base, thereby imparting to the plunger a forward movement in the press-box. When the plunger has moved inward to the desired extent, the trip-lug adjustably mounted on the pin 11, engaged by the hook, will contact with the arm 20, as shown in dotted lines in Fig. 1, and will force the hook 21 out of engagement with the pin, so that the arm 20 maybe returned to its normal position by the spring 22 and the togglelinks may be retracted to their normal position by the spring 18. As the movement to the original position of the parts after a forward movement is caused by springs and is more rapid than the forward movement, a considerable dwell of the plunger will occur after each forward movement, which will give ample time for the introduction into the press of any material to be compressed thereby.

By making the trip-lugs adjustable upon the pins 11 I am enabled to set said lugs in any desired posit-ion upon the pins 11 and thus to insure the action of the lugs to release the hooks 21 from engagement with the pins 11 at any moment which may be desired.

A special advantage of this construction is that by means of it the length of the stroke made by the plunger may be varied up to a certain maximum and that the action of the plunger upon materials of different sorts may be varied to correspond to the nature of the material and the best results in baling secured accordingly. The necessity for varying the degree of pressure used in baling materials of different kinds is well understood, as some materials cannot be greatly compressed without losing much of their value, while others may be compressed to substantially any degree without injurious effects therefrom. It is therefore a matter of special importance to provide in a machine of the type to which this invention relates means for varying the stroke of the plunger. This variation I bring about by means ofthe adjustable trip-lugs hereinbefore described.

In order to prevent too great a shock to the toggle-links when returned to their normal position after a forward movement of the plunger, a yielding stop 24; is mounted near one end of the transverse portion 2 of the base, and at each return movement of the link 17 it contacts with the yieldable stop 24: and relieves the machine of shock, While at the same time diminishing the noise of operation.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination in a baling-press, of a base, a plunger mounted for reciprocation on said base, a pair of toggle-links connected at one end with said plunger and pivotally mounted at the other end on the base, an arm pivotally mounted on one of said links near the point of connection with the other link, a hook on the free end of said arm, a spring between said arm and one of said links, a rotary shaft mounted on said base, a cross-head rigidly attached to said shaft, means on the ends of said cross-head to engage said hook, and a spring to restore the toggle-links to inoperative position after the operation of the plunger.
